Radio wave
Energy can travel through empty space as electromagnetic waves (light, etc.), or as gravitational waves. Changes in the electric and magnetic field are also energy transfers without matter. However, please note that any energy has, by itself, an associated mass.
An electric motor
Electromagnetic waves carry energy through matter and empty space. They consist of two transverse waves - one is the magnetic field and one is the electric field - which travel perpendicular to the direction that the wave is moving.
Move a conductor through a changing magnetic field and run a light off the current generated.
Because it is. Gravitational potential energy is energy stored in the gravitational field, electrical potential energy is energy stored in the electric field, magnetic potential energy is stored in the magnetic field, etc.

Kinetic energy
It is the transfer of mechanical/physical energy to electrical energy. The flowing water rotates a turbine which is attached to a generator and in turn creates an AC field.
At the most basic level, it is through moving a conductor through a magnetic field

The boson particle is usually associated with the Higgs field. It is an energy field that transmits the mass to the things that travel through it.
An electronic currant run through a copper coil will create a magnetic field.

Ruckus means a noisy disturbance. The crows caused a ruckus in the corn field.
Motors convert electrical energy to mechanical energy through moving electric conductors through a magnetic field. Magnets can be permanent magnets or electromagnets.
